In common with other fungal phyla, the Ascomycota are heterotrophic organisms that require organic compounds as energy sources. These are obtained by feeding on a variety of organic substrates including dead matter, foodstuffs, or as symbionts in or on other living organisms. To obtain these nutrients from their surroundings, ascomycetous fungi secrete powerful digestive enzymes that break down organic substances into smaller molecules, which are then taken up into the cell. Many species live on dead plant material such as leaves, twigs, or logs. Several species colonize plants, animals, or other fungi as parasites or mutualistic symbionts and derive all their metabolic energy in form of nutrients from the tissues of their hosts.
Hunter S. Thompson 's Fear and Loathing in America: The Brutal Odyssey of an Outlaw Journalist , which contains hundreds of private letters written by Thompson over the years, contains a letter in which he uses A Modest Proposal' s satire technique against the Vietnam War . Thompson writes a letter to a local Aspen newspaper informing them that, on Christmas Eve, he was going to use napalm to burn a number of dogs and hopefully any humans they find. This letter protests against the burning of Vietnamese people occurring overseas.
Anyone who accepts the free gift of salvation through faith alone in Christ alone receives eternal life at the point of faith or belief. As a child of God (John 1:12), member of the royal family of God and royal priest (I Peter 2:5–7, 9) each believer is eternally secure in Christ. At no time can a believer loose his salvation by irresponsible behavior, or any sin of the mind, speech, and behavior. Eternal security is based upon God’s hold on us, not our hold upon Him (John 10:28–29; Jude 24). Since we are saved by faith it is an act of God’s grace to give eternal life (Ephesians 2:8–9; Titus 3:5). Therefore, it is God’s responsibility to keep us in His love in which He is absolutely capable (Romans 8:38–39). Even if we fall away into sin and deny our salvation, the Lord cannot deny us our salvation although He will deny us rewards (2 Timothy 2:11–13). Believers are assigned titles such as “holy”, “beloved”, and “elect” to indicate their eternal security in Christ (Colossians 3:12; Ephesians 1:7, 2:8–20).
